Excess of .gas may also pass downward 4through the tube 7, and be discharged y through the vents 7, -into the space above the water in the water reservoir. The flow of gas from the carbid box into the water reservoir and the condensing of surplus gas reyents dangerous pressure within the carid box. I

.Acct lene lamps as commonly constructed have t e Water reservoir above the carbid box and the water flows by gravity Afrom the reservoir onto the carbid. This construction is open t0 two serious objections; first that there is constant danger ofv drowning the carbid, and 'second that excessive pressure of as tends to blow water through a vent in t e reservoir, provided for that purpose, and this'blowmg out of the water is l exceedingly annoying to -the Vuser of the lam that? the saturated Wick in the tube 7 and the saturated liber 9, in the hood 8, will prevent downward flow of gas at normal pressure; but in the event of excessive pressure the gas .will force its way through the saturated fibrous material into the water reservoir',

thereby yreducing the pressure Within the carbid box. l The parts 1, 3, .and 4, are closely connected so that Water and gas cannot escape'throughl the joints and the only outlet for-the gas is through the burner 15.

f Having fully described my invention what 4 I claim as new and desire to secure by Letters Patent isf: A

1. In a Iam the 'combination of av tubular body provi ed with a diaphragm 'avwick tube centrally mountedon the diaphragm of In my lamp theconstruction is such? Said nody; a water reservoir detachably connc'ted with said body; a carbid box detachabl' 'connected withv said body and equipped Witli a burner; a perforated hood detachably connected with said 'wick tube and adapted to contain fibrous material contacting with the carbid in the carbid box; a perforated inner tube connected with said hood and. extending through said wick tube into the water reservoir, a nut screwing onto said inner tube; a compressible pad between said nut and the end of said wick tube; fibrous materialfin said hood; and a wick in said wick tube contacting with the Iibrous materia(l in said hood and with said ompressible pa 2: In an acetylene lamp; the combination of a wick tube provided with vents; an inner tube central to vsaid wick tube; a hood on said wiclsr tube; and fibrous material within .said hood and said wick tube ineffective to prevent flow of gas at normal pressure through said wick tube and adapted -to permit gas under excessive pressureto discharge through the vents in said'wick tube.

3` The combination of a central body internally screw-threaded and'having a diaphragm, a carbid box having an extension screwing into said body; a w-ater reservoir having vextension' screwing into said body; a. wick tube centrally mounted on the dlaphragm of said .body and extending intosaid carbid box and said water reservoir; a hood screwing onto said Iwick tube; a perforated central tube connected with said 'hood and extending downward through said wick day -of November 1909.
